Embedded Systems Design Using Event-B Theories

FPGA-Based Embedded systems have a strong impact in everyday life, these systems must be reliable, and their specifications and design should be clear, understandable and must follow specific rules. Therefore, because of these requirements, the method of formal development Event-B based on theories delivered by the Rodin tool-set gives not only a good emphasizing of both static and dynamic aspects for this kind of systems but also a powerful insurance and the guarantee of their accuracy with respect to issues of safety and security by the creation of theories that cover all properties of a system. In this paper we illustrate this concept by modelling NoCs, colored graphs and VHDL language. Thus all these last theories are deployed, discharged and used in Event-B models to represent and enhance the performance of this self-organization reliability solution for the wireless sensors network of NoC-based system.
